Is there any statutory (or other authority) for the above-quoted statement?
That's why I say/said "GENERALLY". For example, where I live I would suggest an appraisal done within six months before/after the owner's passing. Whereas where my relatives live in N.C., property values haven't changed all that much in over 4 years.
Keep in mind also, that while an appraisal may be the best way to go, it's definitely not the only way by far.
